SPECIFIQATION forming part of Letters Eatent No. 640,300, dated January 2, 1900.

Application filed September 18,1899. Serial No. 730,732. (No model.)

To aZ'Z 107mm, 'it may conccrn:

Be it known that I, FREDERIOK J. MILLING- TON, a citizen of the United States, residing at Brushton, in the county of Franklin and State of New York, have invented certain new and useful lmprovements in Acetylene-Gas Generators, of which the following is a specification.

My invention relates to acetylene-gas generators, and has for one of its objects to provide a compact simple form of generator suitable for lamps, piping, or other purposes where only a slnall generator can be used, as well as to purposes demanding a large supply of gas, and therefore larger generators.

Another' object of my invention is to provide an acetylene-gas generator having the reservoir containing the calcic carbid or analogous material subnierged in the liquid slaking agent. p

Another' object of my invention is to combine the valve stem by which the valve through which the liquid slaking agent is admitted to the com pound is opened or shut and the pipe through which the resultant gas passes.

Another object of my nvention is to provide a water-tube from the bottoin of the carbid-reservoir with the valve for adinittin g the liquid slaking agent in its top.

rfhese objects l accomplish in the lnanner and by the means hereinafter more fully described in detail and particularly pointed out in the claim, reference being had to the acconipanying drawings, in which like letters represent like parts in both the views.

Figure 1 is a central sectional view of my invention. Fig. is a plan View on line o: w, Fig. 1.

My invention consists of an outer shell A, closed at the top by means of a screW-cap B and packing C, arranged to close said shell A hermetioally except for an opening in the center of said cap B, in which opening the hereinafter-described cap G is fixed, and for an air-hole 7)' near the edge of said cap B. Firmly secured around the center part of the cap B on the inside and depending from said cap B down into the shell A is a hollow cylindrical tube O, of much smaller diaineter than the shell A. The tube C ends at its lower end in a screw-cap D, of greater diameter than the tube C, though less than the interior diameter of the shell A. The receptacle E for the calcic carbid 01' other analogous material is fitted to be screwed tightly into the sereW-cap D, a gas and air tight joint being forrned by packing d. Through the center of the bottoln of the receptacle E passes a hollow pipe F, which rises to within a short distance of the top of the receptacle E and has at its top a valve-seat f, with a pin-point opening, and around said Valve-seat f a number of wires f' are fixed and extend diagonally downward. Securely fiXed in the opening in the cap B is an interiorly-screW-threaded cap G, which extends a little above and a little below the cap A gas-pipe I-I is exteriorly screW-.

threaded and adapted to be raised or lowered through the cap G by the thulnb-wheel h and is provided with a flange and paeking h' to make an air and gas tight joint and with a check or stop h2 to limit its movement. The lower end of the gas-pipe H is solid and pointed and adapted to fit in the Valve-seat fand close and open said Valve.

The operation of nu y invention is as follows: The receptacle E being charged with calic carbid or other suitable material, the receptacle E is securely screwed into the cap D. The thumb-wheel h is now turned until the gaspipe H is sorewed down tight and its lower end closes the valve-seat f. A suitable amount of the liquid slaking agent is now put into the shell A and the cap B placed on the shell A with suitable packing and screwed tightly down. The apparatus is now ready for use. VVhen it is desired to use the gas, the generator is attached by the upper end of the gasppe I-I to the desired pipe or lamp and the thumb-Wheel 72. screwed up. This adrnits the liquid slaking agent through the pipe F, the wires' servin g to distribute it through the compound. The gas rises into the tube C and thence passes into the pipe H.

Having thus described inyinventiou, what I claiin as new, and desirc to secure by Letters Patent, is;-

An acetylene-gas generator consisting of a Chamber for the slaking fluid, a Chamber for the generating coinpound suspended in said fluid-Chamber, a pipe communicating With said fluid-chamber and extending through the bottom of said com pound-chamber and up ICO into said compound-ehamber, said pipe proto admit the resultant gas, substantially as Vided at its top with Va Valve, a valve-Stern shown and deseribed. Io provided with means for Operating it and ex- In testimony Whereof I hereto affix my sigtending through the upper part of said eomnature in the presenoe of two witnesses.
